Reaction Steps

To a solution of 3-bromo-8-(2,6-dichloro-3-methylaminobenzyloxy)-2-methylimidazo[1,2-a]pyridine (68 mg) and pyridine (0.5 ml) in dichloromethane (2 ml) was added 4-nitrophenyl chloroformate (40 mg) at ambient temperature. After stirring for 1 hour, the mixture was partitioned between dichloromethane and water. The aqueous layer was extracted with dichloromethane twice. The organic layers were combined, washed with water twice and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was crystallized from diethyl ether to give 3-bromo-8-[2,6-dichloro-3-[N-methyl-N-(4-nitrophenoxycarbonyl) amino]benzyloxy]-2-methylimidazo-[1,2-a]pyridine (84 mg) as crystals.
